This alphabetical list of Mental Disorders, also called Psychological Disorders, Psychiatric Disorders, and Mental Illnesses has been gathered from a wide variety of sources including the DSM-IV, DSM 5, ICD-10 Chapter V, and online resources including the Wikipedia page on mental disorders. While we have attempted to make this a complete alphabetical list of mental illnesses, including those that are no longer recognized in either the DSM 5 and ICD-10 Chapter V; there are often local disorders that we are not aware of. There are also older disorders that we have made educated guesses based on our own research.
